DRUM AND CHIMNEY FOR OIL-STOVES.

SPECIFICATION forming part of Letters Patent NO. 474,782, (lated May 10, 18l92.

Application liled December 14, 1891. Serial No. l115,005. (No model.)

To a/ZZ whom it may concern: y

Be it known that I, JOHN M. SToKoE, of Canandaigua, in the county of Ontario and State of New York, have invented a new and useful Improvement in Drums and Chimneys for Oil-Stoves, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

This invention relates more particularly to the matter of supplying air to the llames of the burners; and the object of the invention is mainly to construct the parts so as to render the combustion more perfect.

The invention consists in novel forms of the parts and devices foreffecting the desired improvements in the means for enhancing combustion, and to effect other improvements, all

of which are hereinafter fully described, andl particularly pointed out in the claim.

Referring to the drawings, Figure l is a front elevation of my improved device in part vertically sectioned, as on the dotted line 1 l in Fig. 2. Fig. 2 is a plan of the device partly broken away. Fig. 3 isa side elevation, partly in vertical section, on the dotted line 3 3 in Fig. l,the chimney being partly sectioned on the dotted line 3', viewed as indicated by arrow in Fig. l. Fig. 4 is a cross-section on the dotted line 4. 4. in Fig. l, parts of the second floor being broken away. Fig. 5 is a section on the dotted line 5 5 in Fig. 4.

Referring to the parts shown in the drawings, A is the drum for an oil or other similar stove, made of tin or other sheet metal.

B B are the cones, which are of common construction.

D D are the chimneys.

The drum is formed, in addition to the side walls, with a top plate or sheet d and bottom plate orsheet hand a middle imperforate partition ct, joining both said top and bottom plates and dividing the interior of the drum into two equal compartments, each containing a chimney. The top and the bottom plates d and h are each continuous and airtight and made imperforate except as to openings s in the former to constitute the outlets of the chimneys and the openings n in the latter up through which the cones project.

The bottom plate fits closely around the bases 5o of the cones, as shown.

The drum is preferably provided with a cast-iron base-piece b and a similar cap c, both being continuous and imperforate except as to the openings in the former for the cones and in the latter f or the outlets of the chimneys. The drum is further formed with a horizontal partition or second floor g on a level a little below the tips of the cones, as

shown. This floor is made fast to the interior 6o surfaces of the walls or sides of the drums and to the vertical partition aand is also imperforate save as to two oblong openings Z immediately over the cones. The air to supply the upper portions of the flames is admitted to the interior of the drum through openings f in the walls of drum beneath the second floor g, and its only means of escape is upward through the openings Z around and above the tips of the cones and the llames. 7o

The chimneys, which are of sheet metal, are made rigid with the top plate or sheet d of the drum by ordinary means, and this plate is formed with downturned flanges cto inclose the upper end of the drum and is detachable therefrom. The chimneys, as shown, do not extend downward to the bases of the cones to inclose the latter, but terminate at theirlower ends some distance above the cones. This allows a free circulation of the air admitted 8o through the openings f to and about the upper portions of the flames, which results in a more perfect combustion and a consequent increased intensity of the heat than if the chimneys extended to and inclosed the cones and the flames. The cones and the parts of the stove below them are of common construction, and that portion of the air that is admitted to the flames from beneath comes upward through the cones in the usual manner. The 9o plate d, being tight and without perforation excepting those mentioned, prevents an outflow or escape of the heat of the llames except through the chimneys, which is concentrated under the bottom of the vessel orother devices to be heated, the vessel being placed upon the open support o, which is of common construction.

The partition c, as has been stated, is irnperforate, so that either Haine may be used alone. When both flames are used, this partition is inoperative, save that it constitutes at all times a stilener for the drum.

The'parts of the drum are held together' by the ordinary vertical central bolt p, the partition or,V being Jformed with a detour raround thebolt.

In constructing this improved drum,I usually prefer to place a layer ot asbestus upon the tloor g around the cones.

This drum ispreferably made with opening 7c at the front and at two sides, as shown, the openings being covered by sheets i ot` mica.

Vhat I claim as my invention is In combination with the cones of a stove, a drinn formed with side Walls and air-tight top and bottom plates, and an imperforate vertical partition and pendent chimneys Within the drum over theoones, the drum being further formed with a horizontal partition or Hoor near the tips of the cones, with openings over the latter forming air-passages around the tips of the cones and draft openings through the sides of the drum beneath said horizontal partition, substantially as shown and described.

In witness whereof I have hereunto set my hand, this 28th day of November, in the pres- 3o ence of two subscribing Witnesses.
